The fixtures <br /> are mounted on wood crossorm supports, attached to wood poles opproximotely 45' obove <br /> ground. My projected light level performance for this system is an initial overage footcondle <br /> (FC) of 20FC for the infield, and 15FC for the outfield. Because of crossorm failure, pole <br /> twisting, and lamp performance depreciation; the current light level ot the Shasta fields is <br /> 14FC overage for the infields, and 9FC average for the outfields. <br /> Accepted stondords for recreational softball set by the Illuminating Engineering Society (IES) <br /> exceed the current situotion at the Shasta facility considerably. The IES stondords are set ot <br /> 30FC for the infield and 20FC for the outfield. These light level standards are driven by two <br /> issues: one, playability; and two, liability. At present the Americon Softball Ass. (ASA), the <br /> United States Slowpitch Softball Ass. (USSSA) and Little League require these some standards <br /> as o minimum level strictly for liobility reasons. <br /> OPTIONS TO CONSIDFR: <br /> Because the existing fixtures ore 1000 watts, and are attached to wood crossorms thot are in <br /> dire need of replacement; the utilizotion of these fixtures to upgrade the lighting would cost <br /> more than a new lighting system. Addtionol fixtures (6 to 8 per field) would need to be <br /> purchased, and oll the fixtures would need to be attached to newly fobricoted steel crossarm <br /> supports. Finally, the system would need to be redesigned by a outside engineering <br /> consultont. Listed below ore two Musco optional approaches that will meet the lighting needs <br /> of your facility: <br /> — SC -2 Luminore Assemblies mounted on the existing poles: 26, 1500 watt fixtures <br /> per field, producing o maintained overage FC of 30/20. Equipment cost per field would <br /> be between $14,300 and $15,600; while installation would be between $5,000 and <br /> U 9 A7,000. <br /> �`�; TOTAL COST $19,300 TO $22,600 per field <br /> Independent Representative for: <br /> Official Lighting MUSCO <br /> Consultant to the U.S. <br /> Olympic Committee LIGHTING, INC. <br /> 36USC380 <br />
